Some Results from CRTS To date: Over 1200 confirmed, unique transients discovered (some are detected repeatedly), including: • Over 300 SNe, including some ultraluminous ones • Over 300 CVs, ~ 75% previously unknown, some novae • Over 50 blazars, many previously unknown • About 50 flaring UV Ceti stars (CRTS has a 10 min time cadence) • Many other, high-amplitude variable stars, etc.; many unknown Fast transient (a flare star), CSS080118:112149–131310 4 individual exposures, separated by 10 min Light curve
CRTS Supernova Discoveries • More SNe published in 2009 than any other survey • Extremely luminous and possible pair-production SNe (e.g., SN 2007bi, 2008fz, 2009jh) • Extremely long time-scale SNe, e.g., 2008iy • SNe associated with very faint host galaxies Discovery Baseline CRTS hosts SNF hosts CSS 071218:120153-185822 = SN 2007sr: Ia in the Antennae merger
